Substitute yarn recommendations?

[Phillip]

I found this wondeful pattern online for a stuffed toy lamb

and it calls for about 2 skeins of "Sullivans Fashion Knitting Yarn No. 90187 White".
I wondered if anyone knew of an appropriate substitute, perhaps an alternate brand available in the US? Sullivans is based in Australia, and I don't even want to consider the shipping price!

It would need to be somewhat fluffy, and possibly a worsted weight, going by the needles used and the sts/inch. The 8 ply is like a DK weight. It's knit on smaller needles than you would normally use for these kinds of yarn to be very dense.
